Today were going to talk about poly and Delrin differential bushings for your E30, your, E36ti’s, yours Z3’s. They all compatible.

They all take the same some the sub-frame bushings. They all take the same sub-frames pretty much, theoretically speaking, and the same diff bushing. Today here we got all of our diff bushings that we offer. It’s a Delrin version, which is basically for all-out race guys. It’s good for track application, if you really don’t want that diff to move, Delrin the one for you. It will transmit a little bit more noise, being that it is solid plastic basically.

Then you got your 80-Series, which is the softest poly available. It’s a happy street-friendly durometer hardness. It doesn’t transmit as much noise obviously as the Delrin, being that it will absorb a lot of the noise. It’s really good for autocross, occasional track days, it’s just an all around good bushing. Then you got your 95 which is the hardest poly available. This is the one that we like, it’s the happy medium. It will transmit a ton, a little bit more noise than the 80 but not quite as much as the Delrin. They all basically have the same geometry, they’re solid bushing. As you can see, there is no holes like the factory bushing. The factory bushing have only is connected two or three points, and it was made for comfort, it was design for comfort. Even when you’re going with the softest poly it’s going to be a great upgrade over your stock bushing because it’s attached physically in more area.

They all have a lifetime warranty,all made in USA, here in Westminster California. It’s meant to replace part number 331 71 135242 and that basically is found in E30s, Z3s and E36ti’s, even your 325iIX’s take the same differential bushing, so it’s also compatible with that. Now this will … it’s something that will add responsiveness, it’s going to limit differential movement. A failed if bushing basically sounds like an ape trying to escape from your trunk. There’s usually thump, there’s things going on in the trunk. Usually when you put it in gear, stuff like that, you’re going to hear a bang thump something. Monkey’s trying to get out, usually it’s a because the differential bushing is gone, it’s literally not connected anymore. Installation is simple you will need a press because it does get pressed into your factory differential cover. It’s compatible with M Coupe covers, so even if you’re running on your E30 the upgraded differential cover from the M Coupe or even your E36 or 318ti E36 unit, they’ll accept the M Coupe cover, this will fit it. It’s a great upgrade, very low-cost. It’s a maintenance thing. These things are are quite old now and it’s usually time to replace them. Now this is kind of a while you’re at it thing. If you guys who put in LS1’s, the M60’s, S54 the big motors putting in a little more power. While you look at your differential it’s probably a good idea to look at our secondary diff mount.

This is one of the piece of the components, but basically what this does is it adds a second ear to your differential. Basically this came in later 36’s and stuff like that. BMW basically realized that they should have two years on the differentials. E30s obviously didn’t, they had one ear. This is a great upgrade, very low budget compared to the damage that could occur to your differential. It obviously will require another differential bushing and it will also accept a stock differential bushing. That’s also a good upgrade. Hopefully this made your understanding of E30 diff bushings a little bit better. These Garagistic Poly/Delrin E30, z3 318ti diff bushings are made right here in the USA and come with a lifetime warranty.
